Add Heft to your AI assistant once. Use this address:
https://dailyheft.com/mcp
In your assistant, find the place where you add a custom connector. Some assistants call it a plugin, an app or an MCP server. Paste the address, name it Heft, and sign in with your invite code when asked.
Menus move, so look in the assistant's settings or its customize page. This works in Claude, ChatGPT, Gemini (web app, personal Google account, with Keep Activity on) and Grok (grok.com/connectors).
Then start a conversation and say: “Start a Heft session. Save my mistakes as cards as we go.”
